Title: Anti-panic lock operating device - incorporates spring charged with elastic energy when bolt is moved, and vertically displaceable retainer
Inventor: VALDAJOS GALLEGO LUIS
IPC: E05B15/10
Filed: 1991-06-05

Title: Wheel for aircraft undercarriage - has air guide vanes protruding sideways so that air drives wheel in travel direction on landing
Inventor: SCHEUERMANN JUERGEN
IPC: B64C25/40
Filed: 1992-02-15
Abstract: The wheel comprises a rim(1) accommodating the tyre(2), and a dish-section(3) joining the rim to the hub. The vanes(4) are mounted on the rim and/or dish-section, and protrude outside the area enclosed by the former.

Title: Checking of signals from probes on combustion engine - leading to activation of alarm or reversion to cylinder-selective protection according to lambda signal conformance.
Inventor: SCHUSTER HANS-DIETER DIPL ING
IPC: F02D41/22
Filed: 1992-02-28
Abstract: The method involves measuring and evaluating outputs from probes (10,8) in e.g. exhaust manifolds (9) and individual cylinders (2-7) of an internal combustion engine w.r.t. permissible values. The probes are wired to an electronic signal processor (11). For each operating point of the engine (1) the measured pressure (8) is compared with a characteristic. If significant deviation is detected, cylinder-selective engine protective measures are taken before the same process is applied to lambda measurements (10) leading to overall or selective protection. USE/ADVANTAGE - For e.g. lambda probes, pressure transducers and accelerometers. Reliable detection of misfiring is guaranteed by inexpensive electronic appts.
Patent DE-4206406-A1 (DE)
Title: Cop tray transport arrangement - has supplementary drive to enable incoming cop tray to take precedence at a junction with the main conveyor band
Inventor: KOHLEN HELMUT
IPC: B65G17/32
Filed: 1992-02-29
Abstract: Transport system, with individual cop trays to support cops or tubes, which are carried on plates on a conveyor band. At the junction where trays are transported from one band to another, additional surface contact is provided for the incoming tray to give assisted movement. Pref. the base (5) of the cop tray is carried by friction along the conveyor band. To prevent angular movement of the vertical cop, there is a channel forming a wall at each side of the band, with a profile (8, 8') to cover the edges of the base (5). The plate (10) above the base (5) separates two parallel bands (7, 15) and is shaped to form a passage for the coptray (6) into the junction (16), along with a similar plate (12) to direct the coptray (6) from the band (13). As the coptray (1) on the main conveyor (7) would hold back and cause a disruption in contact with the coptray (6), boost is given to the movement of this tray. A belt around the two wheels (18, 20) touches the side of the base (5) of the coptray (6). By means of the attached disc (17) to the wheel (18), which lies beneath and has contact with the main conveyor band, the belt (19) is driven to give additional impetus to the side of the plate (5) of the coptray (6). The belt may alternatively be driven by a crown wheel arrangement, and spring held friction rollers tensioned against the bottom section of the main conveyor band. This method ensure a better grip and non-slip drive. Should the subsidiary conveyor meet the main band at a right angles, then a curved deflection in the profiled side wall, will provide a resting place for coptray (1), while coptray (6) takes precedence. USE - To prevent a tray on the main conveyor from retaining an incoming tray from a secondary conveyor, when the two meet at the junction.
Patent DE-4207929-A1 (DE)
Title: Support frame for metal chimney pipe - has pairs of support struts each side of pipe and has mounting frame to fix onto wall
Inventor: DIETL ANDREA
IPC: F16L3/20
Filed: 1992-03-12
Abstract: The pipe (1) is gripped on each side by a strut (4a,4b) linked to the apex of a pair of support struts. The inner struts (2a,2b) are under compression while the outer two struts (3a,3b) are under tension. The struts are mounted on a U-profiled support frame (5)  fitted to the wall. The couplings between the struts provide degrees of freedom which allow the chimney pipe to expand when heated. The movement is taken up by the joint. The supports frame is fitted to the wall using insulated supports. USE/ADVANTAGE - Support frame for metal chimney pipe with simple fitting, takes large thermal displacements.
